FAILURE OF A SINGLE CRYSTAL UNDER THE IMPACT OF A CURRENT DOI: 10.22184/2499-9407.2020.21.04.54.55
The article researches fractographic features of fractures of a high-purity Al single crystal after stretching with the introduction of single current pulses, multi-pulse current and without current. Fractographic analysis of fractures indicates the healing of microcrystalline defects with the introduction of a multi-pulse current in comparison with the samples tested with single pulses and without current.

ALGORITHMS MODELING FOR CONTROL OF MOBILE ROBOTS GROUPS BY MEANS OF THE FUNCTIONAL-VOXEL METHOD DOI: 10.22184/2499-9407.2020.21.04.76.81
The article considers an example of a description of one of the algorithms for decentralized navigation of large groups of ORCA agents by means of the functional-voxel method, as well as the case of constructing an area of permissible speeds to prevent collisions for two mobile robots. On the basis of graphic image models, an approach has been developed for constructing the area of permissible speeds of robots on a plane.
